STOVEPlPE-FASTENING.

SPECIFICATION forming part of Letters Patent No. 478,965, dated July 12,1892.

Application filed February 2, 1892.

To all whom it may concern.-

Be it known that 1, JOHN H. JOHNSTON, of Little Rock, in the county ofPulaski and State of Arkansas, have invented a new and usefulImprovement in Stovepipe-Fastenin gs, of which the following is aspecification.

The object of my invention is to provide a simple and practical devicefor connecting the joints of Stovepipe, so as to prevent them frombecoming loose and falling apart, and which shall also effect the firmand secure union of the sections without producing any visible orunsightly effect.

It consists in the peculiar construction and arrangement of partshereinafter shown and described.

Figure 1 is a longitudinal section through Fig. 2 is an inside face viewof these devices.

Inside of each joint of pipe A A and at each end thereof are riveted twodiametrical loops B, formed of flat sheet metal out into strips orribbons and folded in triangular shape, so as to have the two ends I) I)brought together and the middle part b offsetting slightly from theplane of the ends. These loops are connected to the inside of theStovepipe-sections an inch or so from the ends, and they are securelyfastened thereto by a single rivet c, that also passes through andfastens both ends of the loop to each other. This loop, when thusconstructed and secured, has its ends lying fiat against the sides ofthe Stovepipe, while the middle part b is, by the construction of theloop, offset from the walls of the pipe, so as to readily admit aconnecting link or strap of sheet metal to pass between the part b ofthe loop and the side of the pipe. When the two sections of the pipe tobe joined are brought together telescopically, the loops of one sectionare ad usted opposite those on the other, and the sections then areslipped up to their destination. A strip 0 of sheet metal a few incheslong then has its end turned over or back upon itself and is insertedinside the pipe-sections, and the hook thus formed is slipped under andhooked over the loop of the remote section,

and said strip is then passed under the loop of the near section, andafter being drawn tight its other end is bent backwardly over the part bof this loop, so as to connect the two adjacent loops of theStovepipe-sections. This fastening, it will be seen, securely holds thetwo sections, and being within the pipe produces no unsightly effect,and, further, as the strip O, which is bent, is not permanently attachedto the pipe, if it should break from frequent bending and unbending intaking down and putting up the pipe it can easily be replaced by anotherwithout disturbing the attachment of the other parts. Furthermore, itwill be seen that the particular form of the loop causes the ends of thepart b to be inclined, so that if in putting together the pipe-sectionsthe loops do not come exactly opposite each other the connectingstrap 0is free to adapt itself in the loops to an inclined position, as shownby the dotted lines.

The use of my invention will also obviate the necessity of any kind ofhangers for the pipe, and at the same time prevent sagging in horizontalpipes.

I am aware that Stovepipe-sections have been united by a slotted clipriveted to one section and a tongue riveted to the other and adapted tobe extended through the slotted clip and bent over, and that variousother devices have been applied to the pipe-sections externally for thesame purpose, and I therefore limit my invention to the simple andpractical device arranged within the pipe, as shown.

Having thus described my invention, what I claim as new is 1. Thecombination, with two adjacent pipesections, of metal loops riveted tothe said pipe-sections inside of the same near their ends, and aseparate connecting strap or tie bent around the loops and connectingthe op posite pipe-sections, substantially as shown and described.

2. The combination, with two adjacent pipesections, of metal loops B,formed of a strip of sheet-metal bent in triangular shape, with theirends brought together and riveted to signed by me in the presence of twosubscribthe pipe-sections and their middle parts 11 ing Witnesses.oifsett-ing, as described, and a connecting strap or tie bent around theloops, as described, and
